Fuel relay
I was hoping to eliminate the stock fuel relay and use the signal from the computer to my racetronix fuel pump relay but which wire should I use?
I have the A1 (GRN/ WHT) relay wire and the B2 (TAN/ WHT) fuel pump signal from the computer.
This is using the EBL setup and eliminating the MAF relays + if I can the stock fuel relay as well.

Re: Fuel relay
If it is same as stock ; grn/white is the trigger to operate the pump relay
Tan/ white is only feedback ( fuel pump signal) to the ECM showing that pump has voltage available
( and is presumably running )
Typical GM pump wiring ( wire colors vary )
